IMPROVEMENT IN REGENERATIVE HOT-BLAST STOVES.

Specification forming part of Letters Patent No. 218,357, dated August5, 1879; application filed April 30, 1879 patented in England, March 23,1872.

To all whom it may concern.-

Be it known that I, EDWARD ALFRED OOWPER, of Westminster, county ofMiddlesex, England, have invented certain Improvements in RegenerativeHot-Blast Stoves for Heating Air, Steam, and other Gases,of which thefollowing is a specification.

My invention relates to that class of hotblast stoves in which surfacesare arranged for absorbing and giving off heat, on the principledescribed in the Letters Patent of the United States granted to CharlesW. and Frederick Siemens on the 1st day of March, 1864; and the naturethereof consists in combining within the casing of the stove a number offlues and passages, so arranged that the flame or products of combustionshall pass alternately 11p and down therein, and a chamber divided intoa number of small passages, and presenting a large absorbent surface.

Figures 1 and 2 of the accompanying drawin gs show, respectively, avertical section and a sectional plan of an arrangement of aregenerative hot-blast stove, havinglarge vertical passages, in whichthe combustion of the flame takes place, and a regeneratorformed ofbricks placed one above the other. The

gas for combustion enters at the opening A, and the air for combustionat the opening B, causing a flame and products of combustion to passthrough the large vertical passages C, D, and E in the direction shownby the arrows.

After leaving them the heated products of combustion pass downwardthrough the regenerator F, which absorbs the greater part of the heatremaining in them, after which they pass away to the chimney by theopening G. When the valves are reversed the cold blast passes up throughthe regenerator F and through the passages E, D, and O in the oppositedirection to that shown by the arrows, and leaves the stove through theopening H to the hot-blast valve.

English Letters Patent were granted to me for the invention hereindescribed on the 23d day of March, 1872.

Having thus described myinvention, Iclaim and desire to secure byLetters Patent of the United States- The combination, within the casingof a hotblast stove, of a number of upright passages, in which the flameor products of combustion pass alternately up and down, and a chamber orchambers divided into a number of small passages and presenting a largerheat-absorbent surface.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of February, 1879.

EDWARD ALFRED OOWPER.
